8 And יהוה spoke to Mosheh and to Aharon, saying,
9 “When Pharaoh speaks to you, saying, ‘Show a miracle for yourselves,’ then you shall say to Aharon, ‘Take your rod and throw it before Pharaoh, and let it become a serpent.’ ”
10 So Mosheh and Aharon went in to Pharaoh, and they did so, as יהוה commanded. And Aharon threw his rod before Pharaoh and before his servants, and it became a serpent.

12 And they, each one, threw down his rod, and they became serpents. But the rod of Aharon swallowed up their rods.
13 And Pharaoh’s heart was hardened, and he did not listen to them, as יהוה had said.
14 And יהוה said to Mosheh, “The heart of Pharaoh is hard, he refuses to let the people go.
